I went out to feed the goats and let the birds out this morning, and while I was filling water buckets, a great horned owl started hooting really close to the pen. I was going to let the chickens out, but decided to wait until I get done with my morning bus route-----it will be light out then. I did let the ducks and geese out, but am wondering, would a great horned owl be able to carry off one of my ducks? I'm mainly worried about my little black runner hen-------she's quite a bit lighter than the others.
